Authorities said the pot, weighing 2,700 pounds, was found in a vacant warehouse in the 14400 block of West 100th Street. The cache was made up of 385 bundles of marijuana stuffed in boxes of red plastic cups, valued at $1.5 million.

Police said the seizure was the result of a Drug Enforcement Administration investigation that started in Indianapolis.

"It's the biggest I've seen here in Lenexa and I've worked here 32 years," said Capt. Don Krone of the Lenexa Police Department.

Authorities said that probe led to an arrest in the Kansas City area, which in turn, led them to the pot.

"I've never seen this many people around here. Its usually a pretty low-key warehouse district," said Jay Miller, who works in the warehouse next door to the one where the drugs were found.

He said he never had any suspicions about the hundreds of boxes that were being hauled into the warehouse.

"All these companies around here have their own business, so everything is different, from carpet cleaning to landscaping," Miller said. "I didn't think anything was abnormal."

Police have not revealed where the drugs originated. They said they were questioning the person who rents out the warehouse to see if the person was involved in any way.
